Errors with 12_3_X

[michael-pitt]

The following sequence is working:

cmsrel CMSSW_10_6_27
cd CMSSW_10_6_27/src
cmsenv
git clone https://github.com/cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools
cd PhysicsTools/NanoAODTools
scram b
python scripts/nano_postproc.py

The next one throwing ImportError: No module named PhysicsTools.NanoAODTools.postprocessing.framework.postprocessor

cmsrel CMSSW_12_3_0_pre1
cd CMSSW_12_3_0_pre1/src
cmsenv
git clone https://github.com/cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools
cd PhysicsTools/NanoAODTools
scram b
python scripts/nano_postproc.py

I'm trying to run the nanoAOD production with the recent release.

Hi @michael-pitt , I think this has to do with python version. Can you try:-

python3 scripts/nano_postproc.py

Hi @sroychow, Thanks! new errors

tree._ttreereader = ROOT.TTreeReader(tree, tree._entrylist)
TypeError: none of the 5 overloaded methods succeeded. Full details:
  TTreeReader::TTreeReader(TTree* tree, TEntryList* entryList = nullptr) =>
    TypeError: could not convert argument 2
  TTreeReader::TTreeReader(const char* keyname, TDirectory* dir, TEntryList* entryList = nullptr) =>
    TypeError: could not convert argument 1 (bad argument type for built-in operation)
  TTreeReader::TTreeReader(const TTreeReader&) =>
    TypeError: takes at most 1 arguments (2 given)
  TTreeReader::TTreeReader() =>
    TypeError: takes at most 0 arguments (2 given)
  TTreeReader::TTreeReader(const char* keyname, TEntryList* entryList = nullptr) =>
    TypeError: could not convert argument 1 (bad argument type for built-in operation)

I make it work after modifying treeReaderArrayTools.py

tree._ttreereader = ROOT.TTreeReader(tree, tree._entrylist)
...
_ttreereader = ROOT.TTreeReader(tree, getattr(tree, '_entrylist', None))

to

tree._ttreereader = ROOT.TTreeReader(tree)
...
_ttreereader = ROOT.TTreeReader(tree)

I also noticed some errors when using python3 with the later CMSSW versions for modules puWeightProducer.py and btagSFProducer.py. In case anyone else stumbles upon this, I solved it by changing the following in line 63 puWeightProducer.py:
hist.SetDirectory(None) to hist.SetDirectory(0)

And line 249 btagSFProducer.py:
self.algo, os.path.join(self.inputFilePath, self.inputFileName)) to self.algo, os.path.join(self.inputFilePath, self.inputFileName), True)

UPDATE: These issues seems to have been solved properly now. The issue with treeReaderArrayTools was solved by: #293
